Some of most talked-about smartphones right now apart from the iPhone 5 include Samsung's Galaxy S2 and the Motorola Droid 3.

Both Android devices from Samsung and Motorola are offering quite blazing performance.

The Samsung Galaxy S2 is the first Samsung phone to be powered by a dual-core processor. The device runs Android version 2.3 (Gingerbread) and has an incredible 4.3 inch Super AMOLED Plus touchscreen.

Galaxy S2 has sold a whopping three million units outside the U.S., beating the iPhone 4 and upstaging the rumored iPhone 5. The phone is already considered the best smartphone on the planet and is the most successful smartphone in the UK market.

On the other hand, Verizon that carries DROID 3 claims it is the world's thinnest full QWERTY smartphone, and still delivers the power of a dual-core 1 GHz processor for fast multi-tasking.

Droid 3 also runs on Android 2.3 and equipped with a brilliant 4-inch qHD display, a 5-row QWERTY keyboard and 3G Mobile Hotspot capabilities, with the ability to connect up to five Wi-Fi-enabled devices.

Verizon is selling Droid 3 for $199.99 with a new two-year customer agreement. Customers that purchase a DROID 3 will need to subscribe to a Verizon Wireless Nationwide Talk plan and a smartphone data package.

Both phones are offering blazing performance at the hand of dual-core processing power. But, there still could be a thing or two that would make you choose one over the other.
